Ecommerce email and SMS for stores that want Klaviyo's flows without Klaviyo's invoice

Omnisend is an ecommerce marketing platform for small and mid-size online stores that combines email campaigns, prebuilt automation workflows for abandoned cart, welcome, post-purchase and winback, SMS and web push, signup forms and popups, and revenue attribution reporting, priced by contact count with unlimited email sending on its Pro plan.

Overview

Omnisend was founded in Vilnius in 2014 as Soundest, a simple email tool for online stores, and rebranded in 2017 when it went omnichannel. It has stayed effectively bootstrapped: an early convertible note was repaid once the company turned profitable, and it has taken no venture capital since. That independence shows in how the product is positioned. Where Klaviyo sells a customer data platform and reports to public markets, Omnisend sells the specific set of automations that make an online store money and tries to be dramatically cheaper while doing it. More than 150,000 stores run on it, and it holds a 4.8 rating across roughly 2,955 reviews on the Shopify App Store.

The commercial pitch rests on one structural decision: the Pro plan includes unlimited email sends. Standard caps you at twelve times your contact count per cycle, which is the industry norm, but Pro removes the send meter entirely. For a store that mails frequently, runs several concurrent automations, and layers campaigns on top, that is worth real money, because on Klaviyo or Mailchimp high send frequency pushes you up a band regardless of whether your list grew. Modelled monthly cost on Pro runs about $59 at 1,000 contacts, about $150 at 10,000, and about $715 at 50,000, with Standard at roughly $20, $132, and $413 for the same bands.

The billing detail to check before signing is who counts. Omnisend bills both subscribers and non-subscribers who received automated messages. In practice that means people who bought without opting in, abandoned a cart, created an account, or were imported without an opt-in date are billable, and only genuinely unsubscribed contacts are excluded. For a store with a lot of guest checkouts, that can be a meaningfully larger number than the size of your marketing list. It is not as punitive as Mailchimp billing you for people who explicitly left, but it is more inclusive than Klaviyo's marketable-profiles meter.

The other thing to know is that SMS changed materially on 4 May 2026. Subscriptions taken before that date included SMS credits on Pro equal to the monthly plan price, so a $150 plan carried $150 of messages. Subscriptions taken on or after that date get no bundled credits: SMS became Pro-only and a separate metered add-on priced from about $0.007 to $0.009 per US message. If you are reading a comparison written in 2025 that praises the free SMS credits, that offer no longer applies to new customers, and it is a live source of complaint among people who assumed otherwise.

Best for

Small and mid-size ecommerce stores on Shopify, WooCommerce, BigCommerce, or Wix that want the standard revenue-producing flows working quickly and cheaply, especially stores that send frequently enough for Pro's unlimited email sending to pay for itself.

Not the right fit for

Non-ecommerce businesses; the entire product, from the segment builder to the workflow library to the reporting, assumes a store and a catalog, and a consultancy or nonprofit will find most of it irrelevant.
Newsletter operators and creators; there is no paid subscription product, no referral network, and no sponsorship marketplace, so beehiiv, Kit, or Ghost are the right tools.
Large brands that need a genuine customer data platform, warehouse sync, identity resolution, and predictive lifetime value modelling; that is Klaviyo's territory and Omnisend does not pretend otherwise.
Buyers who assumed SMS credits are included; since 4 May 2026 SMS is Pro-only and a separately metered add-on for new subscriptions, so budget for it as a line item.
Procurement processes that require SOC 2 or ISO 27001 on paper; Omnisend publishes a GDPR data processing agreement but no evidence of either certification and no public trust center, so do not assume.

How it works

1
You connect your store. Shopify, BigCommerce, WooCommerce, Wix, Squarespace, Magento, PrestaShop, and a dozen others have native connectors that sync products, orders, carts, and customers, and the onsite script records browsing so that browse abandonment and product-level triggers work.
2
Contacts arrive from the store sync, from signup forms and popups, and from CSV or API import. Segmentation runs over shopping behavior rather than just tags: purchase history, specific products or categories bought, order count and value, campaign engagement, and a lifecycle stage map that classifies where a customer sits between first visit and loyal repeat buyer.
3
Automations are built on a visual workflow canvas, but most stores start from the prebuilt library rather than a blank canvas. Abandoned cart, browse abandonment, welcome, post-purchase, and winback ship as templates, and a workflow can mix email, SMS, and web push steps in one sequence with A or B split nodes and conditional branching.
4
Campaigns and reporting sit on top. One-off campaigns go to a segment with A/B testing on subject, sender, and content, send time optimization is available per contact, and reporting attributes revenue by channel and by campaign so you can see what email produced versus what SMS produced. Reports AI, opened to all paid users in August 2026, answers performance questions conversationally.

Feature breakdown

26 features in 5 modules

Ecommerce automation

The core of the product and the reason a store buys it.

Prebuilt revenue workflows: Abandoned cart, browse abandonment, welcome series, post-purchase, and winback or reactivation ship as templates, so a new store has the standard money-making flows live in a day rather than a fortnight.
Visual workflow builder: Conditional branching, delays, and A or B split nodes on a drag and drop canvas, with triggers from store events, segment membership, and form submissions.
Cross-channel steps in one workflow: A single automation can send email, then SMS, then a web push, with the channel choice conditioned on what that contact has consented to, rather than requiring parallel workflows per channel.
Lifecycle stage mapping: Contacts are classified across a customer lifecycle map from first-time visitor through to loyal repeat buyer, and the stage itself is segmentable and triggerable.
Send time optimization: Per-contact optimal send timing that can be tuned for clicks, opens, or orders. Included on Pro and available as a paid add-on on Standard.

Segmentation and data

Shopping behavior rather than tags, which is what separates this from a general ESP.

Purchase-behavior segments: Segment on products or categories bought, order count, order value, time since last purchase, and total spend, drawn live from the store sync.
Engagement segments: Campaign opens, clicks, and message history across email, SMS, and push, combinable with purchase conditions in the same segment.
AI segment building: Describe the audience you want in plain language and have Omnisend construct the segment definition rather than stacking conditions manually.
Onsite behavior tracking: A store script records product views and browsing so browse abandonment and product-level triggers work against anonymous and known visitors alike.

Content, capture, and campaigns

Strong capture tooling, competent sending.

Drag and drop email editor: Block-based editor with a template gallery and saved brand assets for colors, fonts, and logo, plus support for custom HTML and code.
Dynamic product blocks and AI recommendations: Pull live products from the connected catalog into an email, including recommendations generated from that contact's browsing and purchase history.
Unique discount code generation: Generates single-use codes against the store rather than reusing one shared code that leaks to coupon aggregators, though some paths require codes pre-generated on the store platform.
Popups, flyouts, and embedded forms: A full capture suite including teasers, landing pages, and a fullscreen takeover form type added in August 2026.
Wheel of Fortune: A gamified signup popup that reliably outperforms a plain form on conversion rate, included rather than sold as an add-on.
A/B testing on campaigns and forms: Split test subject line, sender name, sender address, and content with automatic winner selection, and separately A/B test signup forms, which most competitors do not offer.

Channels and reporting

Three channels, one attribution view, and a 2026 pricing change on SMS.

SMS: Pro-only and a separately metered add-on for subscriptions taken on or after 4 May 2026, priced from about $0.007 to $0.009 per US message by volume. Pre-May-2026 subscriptions keep bundled credits equal to the plan price.
Web push: Capped at 500 a month on Free and unlimited on both Standard and Pro, usable as a workflow step alongside email and SMS.
Revenue attribution by channel: Reporting separates what email, SMS, and push each contributed, plus campaign comparison and real-time conversion reporting.
Reports AI: Conversational analytics opened to all paid users in August 2026, answering performance questions without building a report.
Deliverability reporting: Opens, clicks, bounces, unsubscribes, and spam complaints broken out by inbox provider so reputation problems are visible per mailbox.

Platform and developer surface

Adequate rather than deep, with a notable 2026 AI addition.

Versioned REST API: A versioned API at api-docs.omnisend.com covering contacts, events, custom events, products, orders, and carts, with API-key header auth and dated versions alongside the numbered ones.
Webhooks: Event subscriptions for pushing account and contact activity out to your own systems.
MCP connector: A 2026 Model Context Protocol connector, including an official listing in Claude's directory, letting an assistant query campaigns, automations, subscribers, and revenue and draft campaigns, with granular per-area read and write permissions.
Managed shared IP pools: Multiple pre-warmed pools routed by engagement and bounce profile, so small senders inherit pool warmth without a warmup obligation.
Dedicated IP: Available but only recommended above roughly 300,000 emails a week, and Omnisend states plainly that a dedicated IP does not by itself improve deliverability.
Domain authentication: SPF, DKIM, and DMARC configured in-product through DNS records, which is required for Gmail and Yahoo bulk sending compliance.

Use cases

4 documented

Shopify store owner with no email program

All revenue comes from paid traffic, there are no lifecycle emails at all, and Klaviyo has been quoted at a price the store cannot justify at its current volume.

The prebuilt abandoned cart, welcome, and post-purchase workflows go live inside a day off the store connector, and revenue attribution shows what they returned within the first month at a fraction of the Klaviyo quote.

High-frequency sender being penalized by send caps

A 10,000-contact store mails several times a week plus runs four automations, and the twelve-times-contacts send cap on its current platform keeps pushing it into a higher band.

Pro's unlimited email sending removes the meter entirely, so send frequency becomes a marketing decision rather than a billing one.

Store combining email and SMS for launches

Email and SMS run on separate tools, consent is tracked twice, and nobody can say whether the SMS added incremental revenue or just reached people the email already converted.

Both channels run as steps in one workflow off one consent record, and channel-level attribution separates what each actually contributed.

Small team migrating off Klaviyo on cost

A 50,000-profile Klaviyo bill has become one of the largest software line items, and the sophisticated segmentation being paid for is not actually being used.

Omnisend's free Kickstart migration moves contacts, segments, forms, and templates and rebuilds up to four workflows, landing the store at roughly $715 a month on Pro with unlimited sends instead of roughly $720 with a send cap, and with less capability that was going unused anyway.

Pricing

from $0 (free up to 250 contacts), then $16/mo on Standard

Self-serve tiers priced by contact count, where both subscribers and non-subscribers who received automated messages are billable and only unsubscribed contacts are excluded. Standard caps monthly emails at twelve times the contact count; Pro removes the email send meter entirely. SMS is a separately metered Pro-only add-on for new subscriptions since May 2026.

Plan	Price	Includes
Free	$0 per month	250 contacts and 500 emails per month 500 web push notifications Full automation and segmentation features Forms, popups, and landing pages 24/7 live chat and email support Unusually generous on features rather than crippled: you get the real automation builder, and the limit is volume. 24/7 human support on a free plan is close to unheard of.
Standard	$16 at 250 to 500 contacts, about $20 at 1,000, about $132 at 10,000, about $413 at 50,000 per month	Monthly emails capped at 12 times your contact count Unlimited web push Full automation library and segmentation A/B testing on campaigns and forms Send time optimization available as a paid add-on The right tier for stores that send a normal cadence. The 12x send cap is the industry norm and rarely binds below weekly sending.
Pro	$59 flat from the entry band up to roughly 2,500 contacts, about $150 at 10,000, about $715 at 50,000 per month	Unlimited email sending, no send meter Send time optimization included Advanced reporting and Reports AI SMS available as a metered add-on Dedicated Account Expert above $400 a month The flat $59 from the entry band to about 2,500 contacts means a 500-contact store pays the same as a 2,500-contact one, so Pro only makes sense early if you send heavily.
Custom	Quoted per month	High contact volumes Dedicated support and account management Custom sending arrangements

Add-ons

SMS (About $0.007 to $0.009 per US message by volume): Pro-only and separately metered for subscriptions taken on or after 4 May 2026. Subscriptions from before that date keep bundled credits equal to the monthly plan price.
Send time optimization (Paid add-on on Standard, included on Pro)
Dedicated IP (Not published): Only recommended above roughly 300,000 emails a week; Omnisend states a dedicated IP does not by itself improve deliverability.
Kickstart migration ($0): Free for accounts with 250 or more contacts. Omnisend staff migrate contacts, segments, forms, and templates and rebuild up to four automation workflows.

Billing notes

The meter is contacts, and it counts subscribers plus non-subscribers who received automated messages. That includes people who bought without opting in, abandoned a cart, created an account, or were imported without an opt-in date. Only unsubscribed contacts are excluded. For a store with heavy guest checkout, the billable number can exceed the size of your marketing list.
Modelled monthly bill on Standard: roughly $20 at 1,000 contacts, roughly $132 at 10,000, and roughly $413 at 50,000. On Pro: $59 at 1,000, roughly $150 at 10,000, and roughly $715 at 50,000.
Pro's unlimited email sending is the structural advantage. Standard's twelve-times-contacts cap matches the industry norm, but Pro removes the meter, subject to a fair use ceiling commonly described as around sixty times list size, so send frequency stops driving cost.
There is no automatic overage billing. On Standard, hitting the email cap blocks campaign sends and cancels contacts out of automation workflows until the cycle renews or you upgrade, which is a harsher failure mode than a surprise invoice because it silently breaks live automations.
SMS changed on 4 May 2026. New subscriptions get no bundled credits and SMS is Pro-only as a metered add-on. Pre-May-2026 subscriptions are grandfathered with credits equal to the plan price, so older reviews praising free SMS are describing an offer new customers cannot get.
Promotional pricing of roughly 30 percent off the first three months appears regularly on the pricing page, so the first invoice is not a reliable guide to ongoing cost.
The Pro plan is flat at $59 from the entry band up to roughly 2,500 contacts, which means a very small store pays the same as a much larger one. Below that size, Pro only pays off if you send frequently.

Value assessment: Omnisend is the value play in ecommerce email and is priced with a clear view of who it is taking customers from. At 10,000 contacts you are looking at roughly $132 on Standard or $150 on Pro against roughly $150 on Klaviyo's Email plan, which is a wash on headline price but not on terms, because Pro carries no send cap while Klaviyo's allowance is ten times your profile count. At 50,000 contacts the same comparison runs roughly $413 or $715 against roughly $720. So the saving is not enormous at the top, and the real argument is unlimited sending plus getting the standard flows working in a day. Two things erode the case: the inclusive contact meter that bills non-subscribers, and the May 2026 removal of bundled SMS credits, which quietly raised the true cost of the omnichannel pitch the product is named for. For a store that mails often and does not need a customer data platform, it remains the best money in this category.

Strengths & limitations

Strengths

Unlimited email sending on Pro removes the send meter entirely, which is a genuine structural advantage over every contact-plus-send-cap competitor.
The prebuilt ecommerce workflow library gets abandoned cart, welcome, browse abandonment, and post-purchase live in a day, which is where most of the money in store email actually comes from.
Cross-channel steps inside a single workflow, so email, SMS, and web push run from one sequence and one consent record rather than parallel automations.
24/7 live chat and email support with a real human on every plan including Free, with advertised response times measured in minutes. Nothing else in this category does that.
The free plan gives full feature access rather than a crippled subset, so you can genuinely evaluate the automation builder before paying.
Excellent capture tooling: popups, flyouts, embeds, landing pages, a fullscreen takeover form, the Wheel of Fortune gamified popup, and A/B testing on forms as well as campaigns.
Free Kickstart migration for accounts over 250 contacts, including staff rebuilding up to four automation workflows, which removes the largest single migration cost.
Bootstrapped, profitable, and independent since 2014 with more than 150,000 stores and a 4.8 Shopify App Store rating across roughly 2,955 reviews.

Limitations

Billing counts non-subscribers who received automated messages, so guest checkouts and imported contacts without an opt-in date inflate the bill beyond your actual marketing list size.
SMS credits were removed for new subscriptions on 4 May 2026, making SMS a Pro-only metered add-on and quietly raising the cost of the omnichannel proposition.
Hitting the Standard send cap blocks campaigns and cancels contacts out of running automation workflows, which breaks live sequences rather than just charging you more.
No customer data platform, warehouse sync, identity resolution, or predictive lifetime value modelling, so a brand that outgrows the flows will eventually look at Klaviyo anyway.
No SOC 2 or ISO 27001 evidence and no public trust center, which will stall any procurement process that requires either.
WhatsApp is not a native channel despite some review sites claiming otherwise, so the omnichannel story is email, SMS, and web push only.
No first-party product reviews product; Omnisend integrates with third-party review apps rather than shipping its own the way Klaviyo does.
The developer surface is adequate rather than deep: no official language SDKs, and webhook event coverage is thinner than Klaviyo's.
The Pro plan being flat at $59 up to roughly 2,500 contacts penalizes very small stores that need unlimited sending.

Head-to-head comparisons

5 alternatives

Omnisend vs Klaviyo

from $0 (free up to 250 profiles), then roughly $30/mo at 1,000 active profiles

The core comparison in ecommerce email. Klaviyo has the deeper data model, predictive analytics, a real CDP, and the better API, and it stops billing suppressed profiles. Omnisend gets the standard flows working faster and cheaper, offers unlimited sends on Pro, and gives 24/7 human support on every plan. Take Klaviyo when segmentation sophistication is the purchase reason; take Omnisend when you want the money-making flows live this week without the invoice.

Full Omnisend vs Klaviyo comparison

Omnisend vs Mailchimp

from $0 (free up to 250 contacts), then about $13/mo on Essentials at 500 contacts

Omnisend does the ecommerce job Mailchimp does adequately, but properly: better prebuilt store flows, better commerce segmentation, unlimited sends on Pro, and no billing for people who explicitly unsubscribed. Mailchimp is broader outside commerce and has vastly more integrations and better creative tooling. If you run a store, Omnisend. If email is one of five things you need, Mailchimp.

Full Omnisend vs Mailchimp comparison

Omnisend vs Brevo

from $0 (free, 300 emails per day), then $9/mo on Starter at 5,000 emails

Brevo bills emails sent rather than contacts stored, includes transactional email, and hosts in the EU, making it much cheaper for a large list mailed occasionally. Omnisend is the ecommerce specialist with real store flows and revenue attribution Brevo does not attempt. A store should take Omnisend; a business that happens to sell online alongside doing several other things is better served by Brevo's breadth.

Full Omnisend vs Brevo comparison

Omnisend vs ActiveCampaign

from About $15/mo on Starter at 1,000 contacts billed annually (about $19 monthly)

ActiveCampaign has a far deeper general-purpose automation builder, lead scoring, and deal pipelines, and it is the right choice if a human sales process drives revenue. Omnisend is narrower and better at the one thing stores need, at lower cost and with unlimited sends on Pro. Omnisend has nothing resembling lead scoring; ActiveCampaign has nothing resembling a browse abandonment template that works out of the box.

Full Omnisend vs ActiveCampaign comparison

Omnisend vs MailerLite

from $10.80/mo (Comfort, up to 500 subscribers, billed annually; $12 monthly)

MailerLite is cheaper still and has the nicer editor, but its ecommerce automation is basic next to Omnisend's prebuilt store workflows, and it has no meaningful revenue attribution. A store doing low volume where email is a newsletter plus a welcome sequence can happily use MailerLite. Once abandoned cart and post-purchase flows are a revenue line you track, Omnisend earns the difference.

Full Omnisend vs MailerLite comparison

Implementation & onboarding

Setup time: A day to have the core flows running. The store connector installs quickly, syncs products, orders, and customers, and the prebuilt workflows can be enabled with default content immediately. A full migration including domain authentication and testing typically takes around five business days.
Learning curve: Low, and deliberately so. This is the most approachable serious ecommerce marketing tool in the category. The workflow builder is legible to someone who has never built an automation, and the prebuilt library means most stores never start from a blank canvas. The one thing to understand early is the contact-counting rule, because it determines your bill.
Onboarding: Entirely self-serve including the paid tiers, with 24/7 live chat and email support from a human on every plan including Free. Accounts spending above $400 a month get a Dedicated Account Expert. Free Kickstart migration is available for accounts with 250 or more contacts.
Migration notes: Omnisend runs a free Kickstart migration for accounts over 250 contacts in which its staff move contacts, segments, forms, and email templates and rebuild up to four automation workflows, and there is a dedicated Klaviyo data import tool alongside documented Mailchimp paths. Imports require consent and are reviewed, though there is no documented hard requirement to re-confirm an imported list. The genuine friction points are that automations beyond the four free rebuilds are manual work, email HTML rarely ports cleanly between platforms, and historical revenue attribution does not transfer, so your baselines restart.

Platform, API & security

Platforms: Web applicationOnsite tracking scriptNative connectors for a dozen ecommerce platforms
API: Versioned REST API at api-docs.omnisend.com covering contacts, events, custom events, products, orders, and carts, with API-key header auth and both numbered and dated versions; webhook event subscriptions; a published Postman collection; and a 2026 MCP connector with granular per-area read and write permissions, including an official listing in Claude's directory. No official language SDKs.
Compliance: GDPR with a published data processing agreementCCPA-aware privacy policy
Data residency: Data is stored in the EU according to third-party GDPR assessments, though there is no advertised customer-selectable region. Note that no SOC 2 or ISO 27001 certification is evidenced and there is no public trust center, so buyers with certification requirements should ask before committing.
SSO: Not advertised on published self-serve plans.
Security notes: Domain authentication via SPF, DKIM, and DMARC is configured in-product and required for Gmail and Yahoo bulk sending compliance. List quality guidance recommends sending only to contacts engaged in the last six to twelve months, double opt-in, and keeping spam complaints below 0.1 percent, with platform averages cited at roughly 0.3 percent bounce and 0.03 percent complaints.

Frequently asked questions

10 questions

What is Omnisend?

Omnisend is an ecommerce marketing platform founded in Vilnius in 2014, built for small and mid-size online stores. It combines email campaigns, prebuilt automation workflows for abandoned cart, welcome, browse abandonment, post-purchase, and winback, plus SMS and web push, signup forms and popups, and revenue attribution reporting. It is priced by contact count and its Pro plan includes unlimited email sending.

How much does Omnisend cost at 1,000, 10,000, and 50,000 contacts?

On Standard, roughly $20 a month at 1,000 contacts, roughly $132 at 10,000, and roughly $413 at 50,000. On Pro, $59 at 1,000 (flat from the entry band up to about 2,500 contacts), roughly $150 at 10,000, and roughly $715 at 50,000. There is a free plan up to 250 contacts with 500 emails a month, and promotional discounts of around 30 percent on the first three months appear regularly.

Does Omnisend charge me for contacts who never subscribed?

Yes, and this is the billing detail to check first. Omnisend bills both subscribers and non-subscribers who received automated messages, which includes people who bought without opting in, abandoned a cart, created an account, or were imported without an opt-in date. Only genuinely unsubscribed contacts are excluded. For a store with a lot of guest checkouts, the billable number can be noticeably larger than your actual marketing list.

Is email sending really unlimited on Omnisend?

On the Pro plan, effectively yes, subject to a fair use ceiling commonly described as around sixty times your list size. The Standard plan caps you at twelve times your contact count per cycle, which is the industry norm. Unlimited sending on Pro is the platform's main structural advantage, because on most competitors sending more frequently pushes you into a higher band regardless of whether your list grew.

What happens if I hit the send limit on the Standard plan?

Sending stops rather than being billed as overage, and this failure mode is harsher than it sounds: hitting the cap blocks campaign sends and cancels contacts out of running automation workflows until the cycle renews or you upgrade. That means live abandoned cart and welcome sequences break silently, so if you are near the cap, upgrade before you hit it rather than after.

Does Omnisend still include free SMS credits?

Not for new customers. Before 4 May 2026, Pro subscriptions included SMS credits equal to the monthly plan price. Subscriptions taken on or after that date get no bundled credits, and SMS became Pro-only as a separately metered add-on priced from about $0.007 to $0.009 per US message by volume. Pre-May-2026 subscriptions are grandfathered, so older reviews describe an offer you can no longer get.

How does Omnisend compare to Klaviyo?

Klaviyo has the deeper customer data model, predictive analytics, a genuine CDP with warehouse sync, and a stronger API, and it stops billing profiles once they are suppressed. Omnisend gets the standard revenue flows working faster and more cheaply, offers unlimited email sending on Pro rather than a send allowance, and gives 24/7 human support on every plan including the free one. Choose Klaviyo when sophisticated segmentation is what you are buying; choose Omnisend when you want the flows live this week.

Does Omnisend support WhatsApp?

No. Despite claims on some review sites, WhatsApp is not a native Omnisend channel and there is no vendor documentation for it. The omnichannel proposition is email, SMS, and web push. If WhatsApp is a requirement, Brevo and ActiveCampaign both offer it natively.

How hard is it to migrate to Omnisend?

Easier than most, because Omnisend runs a free Kickstart migration for accounts with 250 or more contacts in which its staff move contacts, segments, forms, and templates and rebuild up to four automation workflows. There is also a dedicated Klaviyo import tool. A full migration including domain authentication and testing typically takes around five business days. The residual friction is that automations beyond the four free rebuilds are manual, email HTML rarely ports cleanly, and historical revenue attribution does not transfer.

Is Omnisend certified to SOC 2 or ISO 27001?

There is no public evidence of either, and no public trust center or security page. Omnisend publishes a GDPR data processing agreement, a privacy policy, and consent and double opt-in tooling, and third-party assessments indicate data is stored in the EU. If your procurement process requires a SOC 2 report or ISO certification, ask before committing rather than assuming it exists.

Editorial verdict

Omnisend is the sensible default for a small or mid-size online store that wants the flows that actually make money working quickly, without buying a customer data platform it will not use. The prebuilt workflow library, the cross-channel steps, the capture tooling, and 24/7 human support on every plan including free make it the most approachable serious ecommerce marketing tool in the category, and unlimited email sending on Pro is a real structural advantage over every competitor that caps sends at a multiple of your list. Two caveats deserve weight before you sign: the contact meter counts non-subscribers who received automated messages, which inflates the bill for stores with heavy guest checkout, and the May 2026 removal of bundled SMS credits quietly raised the cost of the omnichannel promise. Buy it if you run a store, mail frequently, and want revenue flows live this week. Look at Klaviyo instead if the reason you are shopping is segmentation depth, and look at MailerLite if your email programme is really just a newsletter.
